@ELECTRIC SIGNAL LAMP FOR RAILWAY SJVI'llCI-IES.v

Application filed September 24,1925. Serial No. 58,390.

710 all whom it may concern:

Be it known that I, CLARENCE J REIGH, a citizen of the'United States,residing at Altoona, in the county of Blair and State of Pennsylvania,have invented certain new and useful Improvements in Electric SignalLamps for Railway Switches; and I do hereby declare the following to bea full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains tomake and usethe same. 7

This invention relates to an electric signal lamp for railway switches.

The prime object is to provide a novel construction wherein the presentsignal lamp and mounting may be used; together with the lamp frame orcasing, so as to readily, inexpensively and expeditiously adapt the mainparts of a present signal lamp supporting and operating structure to thepracticeof the present invention.

Another object is to provide a structure using a novel bracketsubstantially in the form'of a yoke attachable at one end to the lampand at the other end to the stem, and having its bridge vertical andofl'set.

The more specific objects and advantages will become apparent from aconsideration of the description following taken in connection withaccompanying drawings illustrating an operative embodiment.

In said drawings Figure 1 is a view showing the invention in frontelevation;

Figure 2 is a sectional view taken on the line 22 of Figure 1;

Figure 3 is a sectional View taken on the line 33 of Figure 1;

Figure 4 is a sectional view taken on the line H of Figure 1; and

Figure 5 is a detail perspective view of a modified form oflamp-carrying bracket which may be used.

Referring specifically to the drawings, a tie or other support is shownat for a stem 11 disposed in upstanding relation thereto and journaledin a suitable bearing comprising a plate 12 and bracket 12 securedthereto. These parts form the usual construction of a railway switchsignal lamp operating means. The stem 11 has the usual opening 13 inwhich the operating parts are connected in the usual manner in order trock or turn the stem.

In carrying out the present invention, a bracket s provldedas at 1 1',beingayoke or U-shaped, having its bridge 15 vertically lamp shown at18. This lamp or lamp casing 18 is of usual construction and is boltedor otherwise removably secured as at 19 to the arm or plate 17. V

In the present instance, in lieu of the use of oil to illuminatethelamp, an electric bulb 19 is disposed within the lamp and is earnedby a pipe or conduit 20, which 1s stationary and extends up into thecasing 18 at the vertical center thereof. The conduit 20 is irregular toadapt it to its surrounding and wires from a suitable source ofelectricity pass through the'conduit to the lamp 19 in order toilluminate the same. It will be realized that as the pipe or conduit 40is stationar the lamp 18 is adapted to turn relatively thereto with thebracket 14 and that the offset 15 permits the necessary movement of thelamp irrespective of the adjacency or location of the pipe or con duit20.

In using the invention, it will be realized that the ordinary lamp isused, minus its wick and means of oils-upply, that such lamp may besecured in place by the bracket 14; and that the light is supplied bythe bulb 19.

If desired the bracket 14 may be made from a single bar of metalappropriately bent into shape and for instance like the bracket 21 shownin the modified form of Figure 5. Such bracket has an attaching arm 22adapted for connection in any suitable Inanner rigidly to the stem 11and having a plate or arm 23 adapted for connection to the lamp casing18 and also having an opening 24 therethrough to accommodate the pipe orconduit 20.

Various changes may be resorted to provided they fall within the spiritand scope of the invention.

I claim as my invention 1. In combination with a switch-operated stem, abracket secured thereto, a signal lamp carried by the bracket, andstationary means extending to the lamp to form a conduit for electricWires for the illuminating means of the lamp.

2. In combination with a stem operated by a switch, a bracket attachableto the stem, a signal lamp carried by the bracket, said bracket havingan offset portion, a conduit extending to thelamp and adapted as a meansfor passage of conductors therethrough' to the illuminating means of thelamp.

3. In combination with a stem operable by a switch, a bracket having aportion attachable to said stem and having an arm a lamp carried by saidarm, a conduit extending through said arm and into said lamp at aportion thereof coaxial with said stem, said conduit being adapted toaccommodate electric Wires for the illuminating means of the lamp, andthe bridge of said bracket being offset with respect to said portion.

In testimony whereof I affix my signature.

CLARENCE J. REIGH.
